I understand the references, and maybe its that I work in robotics and not web dev. But if the criticism of web dev is that domain knowledge erodes unlike law or medicine, the response shouldn't be that long term stable skills exist such as these two things that have come into prominence in the last decade in go's case, and the last year? in hotwires case

Hotwire is not really a skill. It's a tiny lib that lets your old school server rendered app feel like an SPA. There are obviously other options for your serverside code you can use c if it's up your alley.

fair, I might give it a look if I ever need to create web project. I think ultimately the critique is still valid though. At least in robotics, new knowledge is typically complimentary of existing knowledge. My ML projects don't negate my knowledge of control theory, physics, operating systems, embedded computer architecture, etc.

To be fair in Go's case, it came to prominence at or before the time many of us started. And the Go I learned at the very start of my career (10 years ago) is still usable today.
